Simple Wake-on-lan - Matt - 19.06.2017

Hello,

The wake-on-lan code I am using.

Code:
--[[ Librairy : Wake-on-lan
Author : Matthieu Bouthors

Use with mac address
example : WOL("4c-cc-6a-03-55-eb")

Reminder : only works if the destination is on the same subnet, not routable
]]--

function WOL(target)

 local socket = require("socket")
 local dest_ip="255.255.255.255"
 local port=9
 local udp = assert(socket.udp())
 udp:setoption('broadcast', true)
 
 clean_target = string.gsub(target,":","")
 clean_target = string.gsub(clean_target,"-","")

 hex_target = lmcore.hextostr(clean_target)

 payload = lmcore.hextostr("FFFFFFFFFFFF")
 for i=1,16 do
   payload = payload .. hex_target
 end
 
 assert(udp:sendto(payload, dest_ip, port))

end

one more:

Code:
function wol_send(mac_dest)

 local mac = ''
 for w in string.gmatch(mac_dest, "[0-9A-Za-z][0-9A-Za-z]") do
   mac = mac .. string.char(tonumber(w, 16))
 end
 local udp = require("socket").udp()
 udp:settimeout(1)
 udp:setoption("broadcast", true)
 udp:sendto(string.char(0xff):rep(6) .. mac:rep(16) , '255.255.255.255', 9)
 
end
